Title: Textile pleated fabric - is zigzag pleated in bilateral contact with paper webs with upper one replaced by further paper web for crushing and flattening pleats
Inventor: KLEBER KURT
IPC: D06B11/00
Filed: 1978-12-04
Abstract: Textile pleated fabric is produced by first zig-zag folding the fabric which is over-laid with upper and lower paper webs, then removing the upper paper web and bringing it in contact with an intermediate paper web which the zig-zag folds are crushed to impart to them a flat or arcuate configuration. The rear face of the intermediate paper web is then supplied with heat for heat treating the pleated fabric and fixing the modified pleats. Following heat treatment the paper webs are stripped off the pleated fabric which is wound into a roll under tension to distend the pleats. Fashionable effect is achieved in that body movement of the wearer displays the unprinted fabric portions lying in the troughs of the pleats, relative to the flatter pleated pleated fabrics.

Title: Cylindrical lock suitable for motor vehicle - has cylindrical core comprising two interconnected independently-rotating coaxial parts, each with channel for flat key
Inventor: HEIMANN GEORG DR
IPC: E05B27/00
Filed: 1979-01-12
Abstract: The lock has a cylindrical core divided into two parts across its axis. The channels for the flat key in the part cylinders are rotated w.r.t. one another when the lock is locked such that only the channel in the first part cylinder is accessible to the key. Only after the first part cylinder has been disengaged and rotated by an appropriate angle can the key pass farther and into the channel in the second part cylinder. Both part cylinders are then rotated to unlock the lock. A spring is located between the two part-cylinders, which after the rotation of and pressure from the first part cylinder allows a claw-like linkage between the two part-cylinders to engage. This lock is suitable as a steering wheel ignition or door lock for a motor vehicle.

Title: Tape recorder recorded position indication - has sub-audio code signals recorded onto tape for higher frequency replay during fast forward wind rewind
Inventor: HANSEN JENS DIPL ING
IPC: G11B15/00
Filed: 1979-02-22
Abstract: The tape recorder has fast forward and rewind facilities. Between recorded passages (4, 5) on the tape, identification signals (6, 7, 8) are recorded so that passages may be easily found during fast forward and rewind runs. The identification signal format is for a code (8) to be between satellite signals (6, 7). During fast forward and rewind the format is recognised when picked up by the record/replay head and fed to Schmitt trigger and flip-flop based circuitry. At record/replay speeds, the code signals are below the audio band and are transposed several octaves during fast forward and rewind operations.
